Methylation-associated silencing of SFRP1 in renal cell carcinoma.

Secreted frizzled-related protein 1 (SFRP1) is a candidate tumor suppressor gene located at 8p11.2 and antagonizes the Wnt signaling pathway. Epigenetic inactivation of SFRP1 by methylation of its promoter CpG island has recently been reported in several types of cancers.

Methylation-associated silencing of TU3A in human cancers.

TU3A, located on 3p21.1, was originally identified as a candidate tumor suppressor gene in renal cell carcinoma (RCC). Recently, down-regulation of TU3A expression has been reported not only in RCC but also in other types of cancers.

Microarray-based identification of CUB-domain containing protein 1 as a potential prognostic marker in conventional renal cell carcinoma.

Purpose: Renal cell carcinoma (RCC) is characterized by a variable and unpredictable clinical course. Thus, accurate prediction of the prognosis is important in clinical settings. We conducted microarray-based study to identify a novel prognostic marker in conventional RCC.

Influence of body mass index on prognosis of Japanese patients with renal cell carcinoma.

Objectives: Obesity, a significant risk factor for renal cell carcinoma (RCC), has recently become a public health problem in Japan. In addition, the incidence of RCC in Japan has steadily increased during the past few decades. The objective of the present study was to investigate the relationship of body mass index (BMI) to the prognosis of Japanese patients with RCC.

Synergy of interferon-alpha and 5-fluorouracil in human renal cell carcinoma requires p53 activity.

Objectives: Immunochemical therapy combining cytokines and chemotherapeutic agents is expected to be effective for treating advanced renal cell carcinoma (RCC). We investigated the mechanism underlying the synergism of interferon-alpha (IFN-alpha) and 5-fluorouracil (5-FU) and the effect of p53 status on the synergy of the combined therapy in RCC cell lines.

Methods: The synergy of IFN-alpha and 5-FU was analyzed by isobolographic analysis in five RCC cell lines.

Matrix metalloproteinase-9 polymorphisms and renal cell carcinoma in a Japanese population.

Matrix metalloproteinase-9 (MMP-9) plays a pivotal role in cancer invasion and metastasis. Recently, experimental study has shown that MMP-9 is also implicated in early carcinogenesis. We hypothesized that MMP-9 polymorphisms influence the predisposition to develop renal cell carcinoma (RCC).

Clusterin is a secreted marker for a hypoxia-inducible factor-independent function of the von Hippel-Lindau tumor suppressor protein.

Germline mutations in the von Hippel-Lindau (VHL) tumor suppressor gene predispose people to renal cancer, hemangioblastomas, and pheochromocytomas in an allele-specific manner. The best documented function of the VHL gene product (pVHL) relates to its ability to polyubiquitinate, and hence target for destruction, the alpha subunits of the heterodimeric transcription factor hypoxia-inducible factor (HIF). pVHL mutants linked to familial pheochromocyctoma (type 2C VHL disease), in contrast to classical VHL disease, appear to be normal with respect to HIF regulation.

The expression of NOV and WT1 in renal cell carcinoma: a quantitative reverse transcriptase-polymerase chain reaction analysis.

Purpose: The NOV gene was first identified as an aberrantly expressed gene in avian nephroblastomas induced by myeloblastosis-associated virus. Its expression has been shown to be altered in avian and human nephroblastomas, and to be a target of WT1 regulation. We analyzed the mRNA level of human NOV together with the mRNA level of WT1 in sporadic renal cell carcinoma (RCC).
